311 Condition, etc.) used to be factory functions returning instances of hidden
312 classes (_Thread, _Condition, etc.), because (if Guido recalls correctly) this

Ned Deily657b2de2011-06-28 19:51:30 -0700459- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
460 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
461 interpreter process. This could cause failures in non-Distutils subprocesses
462 and was unreliable since tests or user programs could modify the interpreter
463 environment after Distutils set it. Instead, have Distutils set the the
464 deployment target only in the environment of each build subprocess. It is
465 still possible to globally override the default by setting
466 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
467 greater or equal to the default value, the value with which the interpreter
Ned Deily044369f2011-06-28 20:08:34 -0700468 was built. Also, implement the same handling in packaging.

Victor Stinnerf933e1a2010-10-20 22:58:25 +00002301 variable is not set, the locale encoding is ISO-8859-1, whereas most programs
Georg Brandl4fbc0d82010-11-13 13:25:40 +00002302 (including Python) expect UTF-8. Python already uses UTF-8 for the filesystem

Benjamin Peterson0dc97ed2010-09-21 21:28:47 +00002682- Issue #9901: Destroying the GIL in Py_Finalize() can fail if some other
2683 threads are still running. Instead, reinitialize the GIL on a second call to
2684 Py_Initialize().
2685
Georg Brandl27a28582010-10-10 09:49:21 +00002686- All SyntaxErrors now have a column offset and therefore a caret when the error
2687 is printed.
Antoine Pitroub0b384b2010-09-20 20:13:48 +00002688
Brett Cannonbc2eff32010-09-19 21:39:02 +00002689- Issue #9252: PyImport_Import no longer uses a fromlist hack to return the
2690 module that was imported, but instead gets the module from sys.modules.
2691
Nick Coghlan37ee8502010-12-03 14:26:13 +00002692- Issue #9213: The range type_items now provides index() and count() methods, to
Georg Brandl27a28582010-10-10 09:49:21 +00002693 conform to the Sequence ABC. Patch by Daniel Urban and Daniel Stutzbach.
Daniel Stutzbach9f0cbf12010-09-13 21:16:29 +00002694
Georg Brandl27a28582010-10-10 09:49:21 +00002695- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
2696 with a non-empty format string. This is an effort to future-proof user
2697 code. If a derived class does not currently implement __format__ but later
2698 adds its own __format__, it would most likely break user code that had
2699 supplied a format string. This will be changed to a DeprecationWaring in
2700 Python 3.3 and it will be an error in Python 3.4.
Eric Smithe4d63172010-09-13 20:48:43 +00002701
Antoine Pitrou1df15362010-09-13 14:16:46 +00002702- Issue #9828: Destroy the GIL in Py_Finalize(), so that it gets properly
2703 re-created on a subsequent call to Py_Initialize(). The problem (a crash)
2704 wouldn't appear in 3.1 or 2.7 where the GIL's structure is more trivial.
2705
Amaury Forgeot d'Arcfeb73072010-09-12 22:42:57 +00002706- Issue #9210: Configure option --with-wctype-functions was removed. Using the
2707 functions from the libc caused the methods .upper() and lower() to become
2708 locale aware and created subtly wrong results.
2709
Georg Brandl27a28582010-10-10 09:49:21 +00002710- Issue #9738: PyUnicode_FromFormat() and PyErr_Format() raise an error on a
2711 non-ASCII byte in the format string.
Victor Stinner1205f272010-09-11 00:54:47 +00002712
Amaury Forgeot d'Arcba117ef2010-09-10 21:39:53 +00002713- Issue #4617: Previously it was illegal to delete a name from the local
2714 namespace if it occurs as a free variable in a nested block. This limitation
2715 of the compiler has been lifted, and a new opcode introduced (DELETE_DEREF).
2716
Georg Brandl27a28582010-10-10 09:49:21 +00002717- Issue #9804: ascii() now always represents unicode surrogate pairs as a single
2718 ``\UXXXXXXXX``, regardless of whether the character is printable or not.
2719 Also, the "backslashreplace" error handler now joins surrogate pairs into a
2720 single character on UCS-2 builds.
Antoine Pitroue4a18922010-09-09 20:30:23 +00002721
Antoine Pitrou6e6cc832010-09-09 12:59:39 +00002722- Issue #9757: memoryview objects get a release() method to release the
2723 underlying buffer (previously this was only done when deallocating the
2724 memoryview), and gain support for the context management protocol.
2725
Antoine Pitrou079ce542010-09-08 12:37:10 +00002726- Issue #9797: pystate.c wrongly assumed that zero couldn't be a valid
2727 thread-local storage key.

Antoine Pitrou7980eaa2010-10-06 21:21:18 +00002749- Issue #9759: GzipFile now raises ValueError when an operation is attempted
2750 after the file is closed. Patch by Jeffrey Finkelstein.
2751
Éric Araujo6108bf52010-10-04 23:52:37 +00002752- Issue #9042: Fix interaction of custom translation classes and caching in
2753 gettext.
2754
Éric Araujoef777bd2010-10-05 00:04:20 +00002755- Issue #6706: asyncore.dispatcher now provides a handle_accepted() method
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00002756 returning a (sock, addr) pair which is called when a connection has been
Georg Brandl27a28582010-10-10 09:49:21 +00002757 established with a new remote endpoint. This is supposed to be used as a
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00002758 replacement for old handle_accept() and avoids the user to call accept()
2759 directly.

Lars Gustäbel331b8002010-10-04 15:18:47 +00002761- Issue #9065: tarfile no longer uses "root" as the default for the uname and

2777 conforms to the philosophy of bytes and unicode separation in Python 3. A
2778 test suite has also been added.

Antoine Pitrouc3ed2e72010-09-29 10:49:46 +00002780- Issue #9962: GzipFile now has the peek() method.
2781
Antoine Pitrou3e1fd272010-09-28 21:23:11 +00002782- Issue #9090: When a socket with a timeout fails with EWOULDBLOCK or EAGAIN,
Georg Brandl27a28582010-10-10 09:49:21 +00002783 retry the select() loop instead of bailing out. This is because select() can
2784 incorrectly report a socket as ready for reading (for example, if it received
2785 some data with an invalid checksum).
Antoine Pitrou3e1fd272010-09-28 21:23:11 +00002786
Hirokazu Yamamotocc868d42010-09-28 21:08:38 +00002787- Issue #3612: Added new types to ctypes.wintypes. (CHAR and pointers)

Antoine Pitrou52d42502010-09-21 16:08:27 +00002819- Issue #2643: msync() is not called anymore when deallocating an open mmap
2820 object, only munmap().
2821
Georg Brandl27a28582010-10-10 09:49:21 +00002822- logging: Changed LoggerAdapter implementation internally, to make it easier to
2823 subclass in a useful way.
Vinay Sajip212b5902010-09-21 11:31:32 +00002824
Vinay Sajipc84f0162010-09-21 11:25:39 +00002825- logging: hasHandlers method was added to Logger, and isEnabledFor,
2826 getEffectiveLevel, hasHandlers and setLevel were added to LoggerAdapter.
2827 LoggerAdapter was introduced into the unit tests for logging.
2828
Florent Xiclunaeb19dce2010-09-18 23:34:07 +00002829- Issue #1686: Fix string.Template when overriding the pattern attribute.
2830
Antoine Pitrou98b46702010-09-18 22:59:00 +00002831- Issue #9854: SocketIO objects now observe the RawIOBase interface in
Georg Brandl27a28582010-10-10 09:49:21 +00002832 non-blocking mode: they return None when an operation would block (instead of
2833 raising an exception).
Antoine Pitrou98b46702010-09-18 22:59:00 +00002834
Amaury Forgeot d'Arcd61d0772010-09-17 23:27:09 +00002835- Issue #1730136: Fix the comparison between a tk.font.Font and an object of
2836 another kind.
2837
Vinay Sajip19ec67a2010-09-17 18:57:36 +00002838- Issue #9441: logging has better coverage for rotating file handlers.
2839

Georg Brandl27a28582010-10-10 09:49:21 +00002842- Issue #9854: The default read() implementation in io.RawIOBase now handles
2843 non-blocking readinto() returning None correctly.
Antoine Pitrou328ec742010-09-14 18:37:24 +00002844
Georg Brandl27a28582010-10-10 09:49:21 +00002845- Issue #1552: socket.socketpair() now returns regular socket.socket objects
2846 supporting the whole socket API (rather than the "raw" _socket.socket
2847 objects).
Antoine Pitrou9e0b8642010-09-14 18:00:02 +00002848
Georg Brandl27a28582010-10-10 09:49:21 +00002849- Issue #9853: Fix the signature of SSLSocket.recvfrom() and SSLSocket.sendto()
2850 to match the corresponding socket methods.

Éric Araujod8c73c62011-03-21 03:15:22 +01002852- Issue #9840: Added a decorator to reprlib for wrapping __repr__ methods to make
Georg Brandl27a28582010-10-10 09:49:21 +00002853 them handle recursive calls within the same thread.

Antoine Pitrou6464d5f2010-09-12 14:51:20 +00002859- Issue #9837: The read() method of ZipExtFile objects (as returned by
2860 ZipFile.open()) could return more bytes than requested.
2861
Georg Brandl27a28582010-10-10 09:49:21 +00002862- Issue #9826: OrderedDict.__repr__ can now handle self-referential values:

Raymond Hettingerdc08a142010-09-12 05:15:22 +00002864
Raymond Hettingerfa11db02010-09-12 04:12:42 +00002865- Issue #9825: Using __del__ in the definition of collections.OrderedDict made
Georg Brandl27a28582010-10-10 09:49:21 +00002866 it possible for the user to create self-referencing ordered dictionaries which
2867 become permanently uncollectable GC garbage. Reinstated the Python 3.1
Raymond Hettingerfa11db02010-09-12 04:12:42 +00002868 approach of using weakref proxies so that reference cycles never get created
2869 in the first place.
2870
Victor Stinnercb043522010-09-10 23:49:04 +00002871- Issue #9579, #9580: Fix os.confstr() for value longer than 255 bytes and
2872 encode the value with filesystem encoding and surrogateescape (instead of
Georg Brandl27a28582010-10-10 09:49:21 +00002873 utf-8 in strict mode) . Patch written by David Watson.
Victor Stinnercb043522010-09-10 23:49:04 +00002874
Georg Brandl27a28582010-10-10 09:49:21 +00002875- Issue #9632: Remove sys.setfilesystemencoding() function: use PYTHONFSENCODING
2876 environment variable to set the filesystem encoding at Python startup.
2877 sys.setfilesystemencoding() creates inconsistencies because it is unable to
2878 reencode all filenames in all objects.
Victor Stinner5b519e02010-09-10 21:57:59 +00002879
Georg Brandl27a28582010-10-10 09:49:21 +00002880- Issue #9410: Various optimizations to the pickle module, leading to speedups
2881 up to 4x (depending on the benchmark). Mostly ported from Unladen Swallow;
2882 initial patch by Alexandre Vassalotti.
Antoine Pitrouea99c5c2010-09-09 18:33:21 +00002883
Georg Brandl27a28582010-10-10 09:49:21 +00002884- The pprint module now supports printing OrderedDicts in their given order
2885 (formerly, it would sort the keys).
Raymond Hettingerbad3c882010-09-09 12:31:00 +00002886
Vinay Sajip121a1c42010-09-08 10:46:15 +00002887- Logging: Added QueueHandler class to facilitate logging usage with
2888 multiprocessing.
2889
Georg Brandl27a28582010-10-10 09:49:21 +00002890- Issue #9707: Rewritten reference implementation of threading.local which is
2891 friendlier towards reference cycles. This change is not normally visible
2892 since an optimized C implementation (_thread._local) is used instead.
Antoine Pitrou783eea72010-09-07 22:06:17 +00002893
Amaury Forgeot d'Arc4b6fdf32010-09-07 21:31:17 +00002894- Issue #6394: os.getppid() is now supported on Windows. Note that it will
2895 still return the id of the parent process after it has exited. This process
2896 id may even have been reused by another unrelated process.
2897
Georg Brandl27a28582010-10-10 09:49:21 +00002898- Issue #9792: In case of connection failure, socket.create_connection() would
2899 swallow the exception and raise a new one, making it impossible to fetch the
2900 original errno, or to filter timeout errors. Now the original error is
2901 re-raised.
Antoine Pitrou4b92b5f2010-09-07 21:05:49 +00002902
Georg Brandl27a28582010-10-10 09:49:21 +00002903- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True, and
2904 the passed buffer was exactly 1024 bytes long, the buffer wouldn't be updated
2905 back after the system call. Original patch by Brian Brazil.

Raymond Hettinger435cb0f2010-09-06 23:36:31 +00002907- Updates to the random module:
2908
Georg Brandl27a28582010-10-10 09:49:21 +00002909 * Document which parts of the module are guaranteed to stay the same across
2910 versions and which parts are subject to change.
Raymond Hettinger435cb0f2010-09-06 23:36:31 +00002911
Georg Brandl27a28582010-10-10 09:49:21 +00002912 * Update the seed() method to use all of the bits in a string instead of just
2913 the hash value. This makes better use of the seed value and assures the
2914 seeding is platform independent. Issue #7889.
Raymond Hettinger05156612010-09-07 04:44:52 +00002915
Georg Brandl27a28582010-10-10 09:49:21 +00002916 * Improved the random()-->integer algorithm used in choice(), shuffle(),
2917 sample(), randrange(), and randint(). Formerly, it used int(n*random())
2918 which has a slight bias whenever n is not a power of two. Issue #9025.
Raymond Hettinger05156612010-09-07 04:44:52 +00002919
2920 * Improved documentation of arguments to randrange(). Issue #9379.

Georg Brandl27a28582010-10-10 09:49:21 +00002922- collections.OrderedDict now supports a new method for repositioning keys to
2923 either end.
Raymond Hettingerf45abc92010-09-06 21:26:09 +00002924
Georg Brandl27a28582010-10-10 09:49:21 +00002925- Issue #9754: Similarly to assertRaises and assertRaisesRegexp, unittest test

3071 return characters from the full Unicode range, even on narrow unicode builds
3072 (Py_UNICODE_TOLOWER, Py_UNICODE_ISDECIMAL, and others). A visible difference
3073 in Python is that unicodedata.numeric() now returns the correct value for
3074 large code points, and repr() may consider more characters as printable.
3075
Victor Stinner6c00c142010-08-17 23:37:11 +00003076- Issue #9425: Create PyModule_GetFilenameObject() function to get the filename

3112 type specifier failed to match the str output:
Mark Dickinson5b65df72010-08-01 10:41:49 +00003113
3114 - format(complex(-0.0, 2.0), '-') omitted the real part from the output,

3453
Ezio Melotti57221d02010-07-01 07:32:02 +00003454- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
Georg Brandl62069d32010-07-31 08:56:11 +00003455 start byte and the continuation byte(s) are now considered invalid, instead of
3456 the number of bytes specified by the start byte. E.g.:
3457 '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and replaces
3458 with U+FFFD only the start byte ('\xf1') and the continuation byte ('\x80')
3459 even if '\xf1' is the start byte of a 4-bytes sequence. Previous versions
3460 returned a single u'\ufffd'.

Georg Brandl62069d32010-07-31 08:56:11 +00003462- Issue #9011: A negated imaginary literal (e.g., "-7j") now has real part -0.0
3463 rather than 0.0. So "-7j" is now exactly equivalent to "-(7j)".

3475 dealing with unary minus applied to a constant. The removed code was mutating
3476 the ST, causing a second compilation to fail.

Victor Stinner554f3f02010-06-16 23:33:54 +00003478- Issue #850997: mbcs encoding (Windows only) handles errors argument: strict
Georg Brandl62069d32010-07-31 08:56:11 +00003479 mode raises unicode errors. The encoder only supports "strict" and "replace"
Victor Stinner554f3f02010-06-16 23:33:54 +00003480 error handlers, the decoder only supports "strict" and "ignore" error
Georg Brandl62069d32010-07-31 08:56:11 +00003481 handlers. Patch written by Mark Hammond.
Victor Stinner554f3f02010-06-16 23:33:54 +00003482
Victor Stinner25e8ec42010-06-25 00:02:38 +00003483- Issue #8850: Remove "w" and "w#" formats from PyArg_Parse*() functions, use

3485
Victor Stinner06e49dd2010-06-13 18:21:50 +00003486- Issue #8592: PyArg_Parse*() functions raise a TypeError for "y", "u" and "Z"
Georg Brandl62069d32010-07-31 08:56:11 +00003487 formats if the string contains a null byte/character. Write unit tests for
Victor Stinner06e49dd2010-06-13 18:21:50 +00003488 string formats.
3489
Georg Brandl62069d32010-07-31 08:56:11 +00003490- Issue #7490: To facilitate sharing of doctests between 2.x and 3.x test
Nick Coghlan5e76e942010-06-12 13:42:46 +00003491 suites, the IGNORE_EXCEPTION_DETAIL directive now also ignores the module
3492 location of the raised exception.
3493
Victor Stinner313a1202010-06-11 23:56:51 +00003494- Issue #8969: On Windows, use mbcs codec in strict mode to encode and decode
3495 filenames and enable os.fsencode().
3496
Benjamin Peterson285a6892010-06-22 19:21:52 +00003497- Issue #9058: Remove assertions about INT_MAX in UnicodeDecodeError.
3498
Georg Brandl62069d32010-07-31 08:56:11 +00003499- Issue #8941: Decoding big endian UTF-32 data in UCS-2 builds could crash the
3500 interpreter with characters outside the Basic Multilingual Plane (higher than
3501 0x10000).
Antoine Pitroucc0cfd32010-06-11 21:46:32 +00003502
Georg Brandl62069d32010-07-31 08:56:11 +00003503- Issue #8950: (See also issue #5080). Py_ArgParse*() functions now raise
3504 TypeError instead of giving a DeprecationWarning when a float is parsed using
3505 the 'L' code (for long long). (All other integer codes already raise
3506 TypeError in this case.)
Mark Dickinsonc7301312010-06-10 16:05:10 +00003507
Victor Stinner600d3be2010-06-10 12:00:55 +00003508- Issue #8922: Normalize the encoding name in PyUnicode_AsEncodedString() to
3509 enable shortcuts for upper case encoding name. Add also a shortcut for
3510 "iso-8859-1" in PyUnicode_AsEncodedString() and PyUnicode_Decode().
3511
Georg Brandl62069d32010-07-31 08:56:11 +00003512- Issue #8838: Remove codecs.charbuffer_encode() function. The buffer protocol
3513 doesn't support "char buffer" anymore in Python 3.
Victor Stinner3dcb5ac2010-06-08 22:54:19 +00003514
3515- Issue #8339: Remove "t#" format of PyArg_Parse*() functions, use "s#" or "s*"
Georg Brandl62069d32010-07-31 08:56:11 +00003516 instead. codecs.charbuffer_encode() now accepts modifiable buffer objects
Victor Stinner3dcb5ac2010-06-08 22:54:19 +00003517 like bytearray.
3518
Georg Brandl62069d32010-07-31 08:56:11 +00003519- Issue #8837: Remove "O?" format of PyArg_Parse*() functions. The format is no
Victor Stinner33109a12010-05-28 21:55:10 +00003520 used anymore and it was never documented.
3521
Georg Brandl62069d32010-07-31 08:56:11 +00003522- In str.format(), raise a ValueError when indexes to arguments are too large.
Benjamin Peterson59a1b2f2010-06-07 22:31:26 +00003523
Georg Brandl62069d32010-07-31 08:56:11 +00003524- Issue #2844: Make int('42', n) consistently raise ValueError for invalid
3525 integers n (including n = -909).
Mark Dickinsonf9a5a8e2010-05-26 20:07:58 +00003526
Georg Brandl62069d32010-07-31 08:56:11 +00003527- Issue #8188: Introduce a new scheme for computing hashes of numbers (instances
3528 of int, float, complex, decimal.Decimal and fractions.Fraction) that makes it
3529 easy to maintain the invariant that hash(x) == hash(y) whenever x and y have
3530 equal value.
Mark Dickinsondc787d22010-05-23 13:33:13 +00003531
Mark Dickinsoncc6a9822010-05-21 14:55:26 +00003532- Issue #8748: Fix two issues with comparisons between complex and integer
3533 objects. (1) The comparison could incorrectly return True in some cases
Georg Brandl62069d32010-07-31 08:56:11 +00003534 (2**53+1 == complex(2**53) == 2**53), breaking transitivity of equality.
3535 (2) The comparison raised an OverflowError for large integers, leading to
3536 unpredictable exceptions when combining integers and complex objects in sets
3537 or dicts.
Mark Dickinsoncc6a9822010-05-21 14:55:26 +00003538
Victor Stinner7d79b8b2010-05-19 20:40:50 +00003539- Issue #8766: Initialize _warnings module before importing the first module.
3540 Fix a crash if an empty directory called "encodings" exists in sys.path.
3541
Victor Stinner9ca9c252010-05-19 16:53:30 +00003542- Issue #8589: Decode PYTHONWARNINGS environment variable with the file system
Victor Stinnere039ffe2010-08-15 09:33:08 +00003543 encoding and surrogateescape error handler instead of the locale encoding to
Georg Brandl62069d32010-07-31 08:56:11 +00003544 be consistent with os.environ. Add PySys_AddWarnOptionUnicode() function.
Victor Stinner9ca9c252010-05-19 16:53:30 +00003545
Georg Brandl62069d32010-07-31 08:56:11 +00003546- PyObject_Dump() encodes unicode objects to utf8 with backslashreplace (instead
3547 of strict) error handler to escape surrogates.
Victor Stinner372ac5e2010-05-17 01:26:01 +00003548
Victor Stinnerae6265f2010-05-15 16:27:27 +00003549- Issue #8715: Create PyUnicode_EncodeFSDefault() function: Encode a Unicode
3550 object to Py_FileSystemDefaultEncoding with the "surrogateescape" error
Georg Brandl62069d32010-07-31 08:56:11 +00003551 handler, and return bytes. If Py_FileSystemDefaultEncoding is not set, fall
Benjamin Peterson0c3d21d2010-05-15 17:43:57 +00003552 back to UTF-8.
Victor Stinnerae6265f2010-05-15 16:27:27 +00003553
Victor Stinner59e62db2010-05-15 13:14:32 +00003554- Enable shortcuts for common encodings in PyUnicode_AsEncodedString() for any
Georg Brandl62069d32010-07-31 08:56:11 +00003555 error handler, not only the default error handler (strict).
Victor Stinner59e62db2010-05-15 13:14:32 +00003556
Victor Stinnerb744ba12010-05-15 12:27:16 +00003557- Issue #8610: Load file system codec at startup, and display a fatal error on
Georg Brandl62069d32010-07-31 08:56:11 +00003558 failure. Set the file system encoding to utf-8 (instead of None) if getting
Victor Stinnerb744ba12010-05-15 12:27:16 +00003559 the locale encoding failed, or if nl_langinfo(CODESET) function is missing.
3560
Victor Stinner0964ee12010-04-30 16:48:45 +00003561- PyFile_FromFd() uses PyUnicode_DecodeFSDefault() instead of
Georg Brandl62069d32010-07-31 08:56:11 +00003562 PyUnicode_FromString() to support surrogates in the filename and use the right
3563 encoding.
Victor Stinner0964ee12010-04-30 16:48:45 +00003564
Georg Brandl8569e582010-05-19 20:57:08 +00003565- Issue #7507: Quote "!" in pipes.quote(); it is special to some shells.
3566
Georg Brandl62069d32010-07-31 08:56:11 +00003567- PyUnicode_DecodeFSDefaultAndSize() uses surrogateescape error handler.
Victor Stinnerb9a20ad2010-04-30 16:37:52 +00003568
Benjamin Petersonfb886362010-04-24 18:21:17 +00003569- Issue #8419: Prevent the dict constructor from accepting non-string keyword
3570 arguments.
3571
Victor Stinner14284c22010-04-23 12:02:30 +00003572- Issue #8124: PySys_WriteStdout() and PySys_WriteStderr() don't execute
Georg Brandl62069d32010-07-31 08:56:11 +00003573 indirectly Python signal handlers anymore because mywrite() ignores exceptions

Victor Stinner31be90b2010-04-22 19:38:16 +00003578
Georg Brandl62069d32010-07-31 08:56:11 +00003579- Issue #8485: PyUnicode_FSConverter() doesn't accept byteearray objects

Victor Stinnerdcb24032010-04-22 12:08:36 +00003581
Antoine Pitrou5bc7ec92010-04-21 22:56:22 +00003582- Issue #7332: Remove the 16KB stack-based buffer in
Georg Brandl62069d32010-07-31 08:56:11 +00003583 PyMarshal_ReadLastObjectFromFile, which doesn't bring any noticeable benefit

Antoine Pitroub7fbcd32010-01-16 18:37:38 +00003666- Issue #6690: Optimize the bytecode for expressions such as `x in {1, 2, 3}`,
Georg Brandl62069d32010-07-31 08:56:11 +00003667 where the right hand operand is a set of constants, by turning the set into a

3669 against the constant instead of building a new set each time it is executed (a
3670 similar optimization already existed which turned a list of constants into a

Antoine Pitrou3060c452010-08-13 16:27:38 +00003974 simply clearing the entire cache on overflow to forgetting the least recently
3975 used cached compiled regular expressions. This is a performance win for
Georg Brandl62069d32010-07-31 08:56:11 +00003976 applications that use a lot of regular expressions and limits the impact of
3977 the performance hit anytime the cache is exceeded.

4392 return a result based on the numeric values of the operands; previously they
4393 returned an arbitrary result based on the relative ordering of id(float) and
4394 id(Decimal). See also issue #8188, which adds Decimal-to-Fraction
4395 comparisons.

Barry Warsawd5f9bf52010-03-31 21:36:22 +00004399- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandl62069d32010-07-31 08:56:11 +00004400 argument `-` which tells it to read files to compile from stdin. Each line is
4401 read on demand and the named file is compiled immediately. (Original patch by
4402 Piotr Ożarowski).

4409 Fractions instance now raise TypeError instead of returning True/False. This
4410 makes Fraction <=> complex comparisons consistent with int <=> complex, float
4411 <=> complex, and complex <=> complex comparisons.

Georg Brandl62069d32010-07-31 08:56:11 +00004454- The internals of the subprocess module on POSIX systems have been replaced by
4455 an extension module (_posixsubprocess) so that the fork()+exec() can be done
4456 safely without the possibility of deadlock in multithreaded applications.

Georg Brandl62069d32010-07-31 08:56:11 +00004458- subprocess.Popen now has restore_signals and start_new_session features. The
4459 default of restore_signals=True is a new behavior compared to earlier Python
4460 versions. This means that signals such as SIGPIPE are not ignored by default
4461 in subprocesses launched by Python (Issue #1652).

Georg Brandl62069d32010-07-31 08:56:11 +00004553 :class:`zipfile.ZipExtFile` class used to represent files stored inside an
4554 archive. The new implementation is significantly faster and can be wrapped in
4555 a :class:`io.BufferedReader` object for more speedups. It also solves an
4556 issue where interleaved calls to `read()` and `readline()` give wrong results.
4557 Patch by Nir Aides.

Ronald Oussorenb6ee4f52010-07-23 13:53:51 +00004954- Issue #7900: The getgroups(2) system call on MacOSX behaves rather oddly
Georg Brandl62069d32010-07-31 08:56:11 +00004955 compared to other unix systems. In particular, os.getgroups() does not reflect
4956 any changes made using os.setgroups() but basicly always returns the same
4957 information as the id command. os.getgroups() can now return more than 16
4958 groups on MacOSX.

5314 threads could return successfully while some Thread objects were still

Antoine Pitroue4501852009-05-14 18:55:55 +00005550- Issue #5006: Better handling of unicode byte-order marks (BOM) in the io
5551 library. This means, for example, that opening an UTF-16 text file in
5552 append mode doesn't add a BOM at the end of the file if the file isn't
5553 empty.
5554
R. David Murray74b89242009-05-13 17:33:03 +00005555- Issue #4050: inspect.findsource/getsource now raise an IOError if the 'source'
5556 file is a binary. Patch by Brodie Rao, tests by Daniel Diniz. This fix
5557 corrects a pydoc regression.
5558
Georg Brandl5f90d792010-08-01 22:31:05 +00005559- Issue #5955: aifc's close method did not close the file it wrapped,

Benjamin Peterson5c5f3de2009-05-06 20:43:28 +00005601*Release date: 2009-05-06*
Benjamin Petersonbd35b032009-04-04 23:16:41 +00005602
5603Core and Builtins
5604-----------------
5605
Mark Dickinson865e01a2009-05-07 16:37:01 +00005606- Issue #5914: Add new C API function PyOS_string_to_double, and
5607 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
5608
Eric Smith741191f2009-05-06 13:08:15 +00005609- Issue #3382: float.__format__, complex.__format__, and %-formatting
5610 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
5611 affects nan -> NAN and inf -> INF.
5612
Mark Hammond5a607a32009-05-06 08:04:54 +00005613- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
5614 in all operations, including splitdrive, split, etc. splitunc() now issues
5615 a PendingDeprecation warning.
5616
Eric Smith63376222009-05-05 14:04:18 +00005617- Issue #5920: For float.__format__, change the behavior with the
5618 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
5619 to be like 'g' but with at least one decimal point and with a
5620 default precision of 12. Previously, the behavior the same but with
5621 a default precision of 6. This more closely matches str(), and
5622 reduces surprises when adding alignment flags to the empty
5623 presentation type. This also affects the new complex.__format__ in
5624 the same way.
5625
Martin v. Löwis011e8422009-05-05 04:43:17 +00005626- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
5627
R. David Murrayb18500d2009-05-04 22:59:07 +00005628- Issue #5890: in subclasses of 'property' the __doc__ attribute was
5629 shadowed by classtype's, even if it was None. property now
5630 inserts the __doc__ into the subclass instance __dict__.
5631
Antoine Pitrou244651a2009-05-04 18:56:13 +00005632- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
5633 sequences. Patch by Nick Barnes and Victor Stinner.
5634
Martin v. Löwise0a2b722009-05-10 08:08:56 +00005635- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00005636
Benjamin Petersond2e0c792009-05-01 20:40:59 +00005637- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
5638 received a new method, detach(). detach() disconnects the underlying stream
5639 from the buffer or text IO and returns it.
5640
Mark Dickinson33841c32009-05-01 15:37:04 +00005641- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
5642 floats with absolute value over 1e50. Also remove length
5643 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
5644 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00005645
Eric Smith741191f2009-05-06 13:08:15 +00005646- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00005647 format(complex(1, 2./3), '.5') now produces a sensible result.
5648
Mark Dickinsond3ca5572009-04-29 18:47:07 +00005649- Issue #5864: Fix empty format code formatting for floats so that it
5650 never gives more than the requested number of significant digits.
5651
Eric Smith6dc46f52009-04-27 20:39:49 +00005652- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
5653 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
5654
Eric Smithcc32a112009-04-26 21:35:14 +00005655- Issue #5835: Deprecate PyOS_ascii_formatd.
5656
Martin v. Löwis71efeb72009-04-26 01:02:07 +00005657- Issue #4971: Fix titlecase for characters that are their own
5658 titlecase, but not their own uppercase.
5659
Benjamin Peterson193152c2009-04-25 01:08:45 +00005660- Issue #5283: Setting __class__ in __del__ caused a segfault.
5661
Mark Dickinsonad476da2009-04-23 19:14:16 +00005662- Issue #5816: complex(repr(z)) now recovers z exactly, even when
5663 z involves nans, infs or negative zeros.
5664
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00005665- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00005666
Mark Dickinsone6a076d2009-04-18 11:48:33 +00005667- Issue #1869 (and many duplicates): make round(x, n) correctly
5668 rounded for a float x, by using the decimal <-> binary conversions
5669 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
5670 consistently agrees with format(x, '.2f').
5671
Benjamin Petersonae937c02009-04-18 20:54:08 +00005672- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
5673 some builtin types.
5674
Eric Smith0923d1d2009-04-16 20:16:10 +00005675- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
5676
Eric Smith35e84722009-04-16 20:21:28 +00005677- Issue #5515: str.format() type 'n' combined with commas and leading
5678 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00005679
5680- Implement PEP 378, Format Specifier for Thousands Separator, for
5681 floats.
5682
Mark Dickinson3370cce2009-04-17 22:40:53 +00005683- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005684 1e11, not 1e12. This avoids printing 13 significant digits in
5685 situations where only 12 of them are correct. Example problem
5686 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
5687 long time.)
5688
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005689- Issue #1580: On most platforms, use a 'short' float repr: for a
5690 finite float x, repr(x) now outputs a string based on the shortest
5691 sequence of decimal digits that rounds to x. Previous behaviour was
5692 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00005693 Another minor difference is that the new repr switches to
5694 exponential notation at 1e16 instead of the previous 1e17; this
5695 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005696
5697 There's a new sys attribute sys.float_repr_style, which takes
5698 the value 'short' to indicate that we're using short float repr,
5699 and 'legacy' if the short float repr isn't available for one
5700 reason or another.
5701
5702 The float repr change involves incorporating David Gay's 'perfect
5703 rounding' code into the Python core (it's in Python/dtoa.c). As a
5704 secondary consequence, all string-to-float and float-to-string
5705 conversions (including all float formatting operations) will be
5706 correctly rounded on these platforms.
5707
Georg Brandl5f90d792010-08-01 22:31:05 +00005708 See issue #1580 discussions for details of platforms for which
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005709 this change does not apply.
5710
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00005711- Issue #5759: float() didn't call __float__ on str subclasses.
5712
Georg Brandlabc38772009-04-12 15:51:51 +00005713- The string.maketrans() function is deprecated; there is a new static method
5714 maketrans() on the bytes and bytearray classes. This removes confusion about
5715 the types string.maketrans() is supposed to work with, and mirrors the
5716 methods available on the str class.
5717
R. David Murraydc6da8a2009-04-09 22:16:43 +00005718- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
5719 its clarity and its speed.
5720
Georg Brandl65ce6ad2010-09-05 17:32:31 +00005721- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add ``do { ... } while (0)``
Matthias Klose091c7b12009-04-07 13:24:27 +00005722 to avoid compiler warnings.
5723
Walter Dörwald8dc33d52009-05-06 14:41:26 +00005724- Issue #3739: The unicode-internal encoder now reports the number of characters
5725 consumed like any other encoder (instead of the number of bytes).

5873 insufficient checks in accessors of Exception.__context__.
5874
Guido van Rossum0ad59d42009-03-30 22:01:35 +00005875- Issue #5604: non-ASCII characters in module name passed to
5876 imp.find_module() were converted to UTF-8 while the path is
5877 converted to the default filesystem encoding, causing nonsense.

5882 the end sys.path, for compatibility with the system install of Python.
5883
Antoine Pitrou3a652b12009-03-23 18:52:06 +00005884- Issue #4688: Add a heuristic so that tuples and dicts containing only
5885 untrackable objects are not tracked by the garbage collector. This can
5886 reduce the size of collections and therefore the garbage collection overhead
5887 on long-running programs, depending on their particular use of datatypes.
5888

5956
Lars Gustäbel42e00912009-03-22 20:34:29 +00005957- Issue #5068: Fixed the tarfile._BZ2Proxy.read() method that would loop
5958 forever on incomplete input. That caused tarfile.open() to hang when used
5959 with mode 'r' or 'r:bz2' and a fileobj argument that contained no data or
5960 partial bzip2 compressed data.
5961
Mark Dickinson79f52032009-03-17 23:12:51 +00005962- Issue #2110: Add support for thousands separator and 'n' type

6030 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
6031 evaluation loop is compiled with a new dispatch mechanism which gives
6032 speedups of up to 20%, depending on the system, on various benchmarks.

Antoine Pitrou8d4e5052009-01-13 22:59:11 +00006047- Issue #4935: The overflow checking code in the expandtabs() method common
6048 to str, bytes and bytearray could be optimized away by the compiler, letting
6049 the interpreter segfault instead of raising an error.

Antoine Pitrou8043cf82009-01-09 19:54:29 +00006073 having been closed (for instance, a read() call could return some
6074 previously buffered data). Patch by Dmitry Vasiliev.
6075
Antoine Pitrou05608432009-01-09 18:53:14 +00006076- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
6077 flag to work properly. Furthermore, when specifying -u, the text stdout
6078 and stderr streams have line-by-line buffering enabled (the default being
6079 to buffer arbitrary chunks of data).
6080
Raymond Hettinger35631532009-01-09 03:58:09 +00006081- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
6082 instead of ints (reducing its size from 4 to 8 times thereby reducing
6083 Python's overall memory).
6084
Antoine Pitroud35cbf62009-01-06 19:02:24 +00006085- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
6086 an existing .py counterpart, override the co_filename attributes of all
6087 code objects if the original filename is obsolete (which can happen if the
6088 file has been renamed, moved, or if it is accessed through different paths).
6089 Patch by Ziga Seilnacht and Jean-Paul Calderone.
6090
Antoine Pitrouc3b39242009-01-03 16:59:18 +00006091- Issue #4580: Fix slicing of memoryviews when the item size is greater than
6092 one byte. Also fixes the meaning of len() so that it returns the number of
6093 items, rather than the size in bytes.
6094
Martin v. Löwis5c88d812009-01-02 20:47:48 +00006095- Issue #4075: Use OutputDebugStringW in Py_FatalError.

6482
Antoine Pitrou08838b62009-01-21 00:55:13 +00006483- Issue #5008: When a file is opened in append mode with the new IO library,
6484 do an explicit seek to the end of file (so that e.g. tell() returns the
6485 file size rather than 0). This is consistent with the behaviour of the

6516 appropriately when it is being used via socket.makefile() objects
6517 rather than delaying the close by waiting for garbage collection to do it.
6518
Raymond Hettingerb8baf632009-01-14 02:20:07 +00006519- Issue #1696199: Add collections.Counter() for rapid and convenient
